How do butterfly’s wings shine? Like almost all other butterflies, the Morpho has wings covered with scales. Typically, pigmentation patterns across these scales generate wing colors, but a Morpho‘s scales deploy an additional feature.

On top of their scales, Morpho butterflies have countless tiny, tree-like structures with suspended branched arms that manipulate light waves. Spacing among the branches helps match targeted light-wavelengths, like blue for example. Repeated reflections of the same wavelength cause interference effects that, when viewed from certain angles, generate stunning iridescence.
